Metabolite amyloid-like fibrils interact with model membranes

Chem Commun (Camb). 2018 May 1;54(36):4561-4564. doi: 10.1039/c8cc01423j.

Abstract

Amyloid-like structure formation by various metabolites represents a significant extension of the amyloidogenic building block family. Similar to protein amyloids, metabolite amyloids induce apoptotic toxicity, a process that was linked to membrane association. Here, we demonstrate that metabolite amyloids interact with model membranes and study the mechanism by molecular dynamics.
